Thank you for your ideas.

We do have mains power but I don't want to run 240v across a garden with children, pets, livestock and heavy rain!

I think the 12v pump is the way forward as John C Daley correctly pointed out a Ram pump needs a higher flow than we have.

I am thinking about an inline or external pump as they are more durable.

What are the differences between an 'impeller' and 'diaphragm' in terms of:

Durability
efficiently
Ability to slow down the flow rate to reflect our low flow springs.

Thank you

Not a proper aquaponic question, but very similar. We have a 1/3 acre garden on the west coast of the Scottish Highlands

We are building a duck coop (with chickens) with a couple of 50 US gallon pools (200L) at the top of a 100ft'ish (35m) slopping plot. We have 3 low flow springs about 16ft  away and 7 ft lower down. The biggest spring flows about 1/4 to 1/2 gallon a minute depending on rainfall but has never run dry, the others are much more variable and never more than 1/4 gallon max often much less. We'd like to use a non powered or 12v pump and we have a 100w solar panel.

We would to pump water up to the ducks and then drain down through some biofilters, swirl filters into bullrush, duckweed beds etc to clean up the duck fouled water before pumping it back up again. Aim is to generarat some duck and chicken feed.

Vertical distance would be about 12ft and horizontal would be about 150ft. I have 12 large blue 55-gallon barrels to act as storage and header tanks.

We are not looking for fast flow, just enough to gently clean and refill duck pools and keep the sediment flowing into the growing beds.

The obvious answer is to put the duck coop below the spring line, but that means putting it in a prime veggie growing area on a small 1/3rd acre plot and having the poultry close to the neighbour's houses who may not appreciate rowdy poultry, even though they are very happy to have ducks and chickens as neighbours I do not want to test their patience at 4am on a summer morning.

In a land famous for its rains, we can go for several weeks with no rain, so rainwater feeds to the header tanks would not be reliable in the spring and autumn when we have lower rainfall, unless we built a HUGE tank.

What pump could deal with such a low volume?

I assume a DIY Ram pump would need more flow.

A Venturi pump would need more pressure?  https://www.youtube.com/watch?v=CKueWzfmN_s

So we thought a 12v pump attached to a float switch at the downhill storage that pumps up to the header tank.  Any ideas or suggestions welcome.  The photo shows the children checking the water quality of the one of the smaller springs!

Thank you.

Ahhh this is becoming clear now.

I can not access the non gmail account as it was unilaterally shut down by our internet provider when we moved several years ago. We do have a kickstarter account with our gmail address, I error I must have given you the wrong account with the  outdated email account.

My apologies!

So what do you want me to do?

Give your the correct gmail address and / or the vimeo account that goes with the gmail address?

The email on the Vimeo account is not a gmail one, my fault I have left a very old email address on there, but the Kickstarter email address is the correct one.

So how do we sort this?

Very sorry to be causing you so many problems, I am amazed at how much information you got on my accounts!

Problem is my gmail account just keeps on telling me I have no email with the words kickstarter, vimeo or rocket in them, even in spam, so while the email you kindly sent with the vimeo link is highly likely to be in my gmail account I have no way of finding it!

So I begain looking through the spam folder email by email, only to find gmail seems to only keep 104 spam(s)

Again your vimeo voodoo skills are amazing but I can only find your brilliant World Domination Gardening vids, nothing on cob!

So, despite your valiant efforts at plugging the huge gape in my IT skills I am still left with no ability to watch your latest work!

Dear Paul,

Thank you for your reply to my message on Kickstarter, which directed me to this thread.

May I re-ask the question having read the post?

So this is my question:



"Hello!

I pledged to your great project for the streaming option but do not seem to had a link to vimeo?

Have I just misunderstood this or have I been missed, or just missed an email?

With thanks,

Simon"

My email account and my memory both seem to think we have had no message asking for a Vimeo account, so am at a loss on how to access the streaming versions!


With thanks,

Simon
